Rectangular box connectors are available in a variety of configurations (plugs, receptacles, jackposts, jackscrews, and more) with many contact arrangements to choose from. There are also several different termination types (crimp, solder, flex, circuit board, and wrap post) and protective versions (hermetic and environmental). Such a wide selection of construction types will ensure that you can find the right rectangular connector with proper mating to meet your needs.

All rectangular connectors are packaged and shipped with strict quality control to prevent damage and ensure exceptional performance. They are ideal for commercial, military, defense, and aerospace industries with any type of circuit board application, such as medical equipment, aircraft cabins, satellites, robotics, etc.

RF Connectors

AE Petsche’s broad coaxial connector offering covers a frequency range from DC-65GHz. Our connectors, depending on series selected, are in the true Radio Frequency range (up to 1 GHz), the microwave range (up to 20 GHz) or the millimeter wave (exceeding 20 GHz). They are available in multiple series styles and configurations. We carry over 700 QPL compliant military standard series connectors, adaptors, attenuators, dummy loads and terminations. These specifications provide a benchmark for interface intermatability, material standards, electrical and environmental performance criteria in an effort to ensure consistency, repeatability and functionality across multiple manufacturers.

In addition to supplying the military and defense market, our coaxial connector line is commonly used for high-frequency data transmission, wireless telecommunications, antennas, radios, microwave components, computer networks and more, servicing the medical, defense, aerospace, marine, automotive, rail, broadcast industries and others.

Our coaxial connectivity solutions are available in 50 & 75 Ohm impedance values and feature a variety of mechanical interface options, providing flexibility to accommodate package size and performance goals. All of our connectors accommodate a variety of cable types including flexible, semi-rigid and conformable.

You can also choose from a selection of base materials, finishes, terminations, and mounting styles which are all rigorously tested in accordance to the required test standards. Standard and semi-standard coaxial connectors, along with custom connector configurations and cable assemblies, are available.

Crosstalk in cellular and radar applications continues to be an issue that system shielding does not fully control. Many of our connectors are specifically designed to improve Passive Intermodulation Measurement {PIM} performance so that drop calls and interference in signal transmission is minimized.
